"A researcher collects 25 data points that yield a mean of 8.164 and a standard deviation (based on N – 1) of 2.237. What is the standard error for the distribution of means?"

Standard error for the distribution of means = 0.4474

Step-by-step explanation:

Standard error for the distribution of means is given as

σₓ = σ/√n

where σ = standard deviation = 2.237

n = sample size = 25

σₓ = (2.237/√25)

σₓ = 0.4474

Hope this Helps!!!

The standard error for the distribution of means is 0.457.

Step-by-step explanation:

The standard error for the distribution of means is given as sample standard deviation divided by the square root of (N - 1)

sample standard deviation = 2.237

N is sample size = 25

Standard error = 2.237 ÷ sqrt(25 - 1) = 2.237 ÷ sqrt(24) = 2.237 ÷ 4.899 = 0.457

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
